TV uses <3A of power.

oh, ok!!

Why would the blue power light flash now that I have changed the capacitors?

It probably gets the correct 5V now but there are other problem.

Oh, I see. We measured the 24v and it was fine, weird.

If you are getting steady 24V for the inverter board, that means the main board is sending the PS ON to turn on the PFC and the 24VDC power supply section OK.

That's what my friend kept telling me. He assured me that the power supply was good when I left his shop. I watched and helped test the 24v and it looked ok to me.

I dusted off the old reading glasses and tester! ha! When I read the 5v, it drops and goes to 0. I tried a few different things and I might have to go back to those original capacitors being bad?

OK, I am confused:
"I dusted off the old reading glasses and tester! ha! When I read the 5v, it drops and goes to 0. I tried a few different things and I might have to go back to those original capacitors being bad?" I though that you do not have 5V.
So what do we really have at this point?

Sorry about the confusion. I used to be able to test this stuff but, with old age comes bad eyes, ha!

I plug the power in and try to read the 5v pins. I get a reading and then it drops to 0?

Re: Sceptre X32GV-Komodo Turns on but then turns back off, after logo, with some flic

OK, so now you do not have the 5V or 24V either, correct?
If that is the case, just power up the power supply board by itself with nothing else connected and see if the 5V is present, so I assumed that the two start up caps are replaced.

I do not have power at either. It's odd because I watched and helped test both after changing out the capacitors.

So I have a Sceptre X322BV-Hdr8WX2262P71, it comes on, you see the logo for a second or two then the screen goes black, if you leave it on for a minute you will hear sound of what ever tv show is on? Where do I start?
